Does the Nec allow grounding electrode conductor to be run in conduit that has other conductors in the conduit and what code section?
No, the bare copper grounding conductor can not be in a conduit with other conductors. It can be in conduit by itself to provide mechanical protection for the wire.
How many12 gauge wires can you use in a 1 inch conduit?
The NEC allows 26.
Can you run different phases in the same conduit?
In the US, the National Electrical Code (NEC) will allow you to install single phase and three phase systems in the same conduit.
What is the depth requirement for an under ground electrical mains cable?
Metal conduit must be buried to at least 6 inches. Non-Metal conduit must be buried to at least 18 inches. Direct bury wire must be buried to at least 24 inches. This is what the NEC requires but your local codes may be even deeper. Check with your local utility to see what they require.
What is the maximum allowable conductor fill of any trade size conduit used as a raceway?
It depends on the wiring, the current load in the wiring , and the distance. The NEC Code book has the charts for this.And the size of the conduit.
Can you weld rigid conduit?
Welding is not allowed by the NEC (United States' code).

What size conduit is needed for a 100 amp service according to the nec?
According to the NEC, a minimum of 1.5-inch conduit is required for a 100 amp service. It is important to follow local codes and regulations which may vary. Consulting with a licensed electrician is recommended for proper installation.

What is the code for strapping EMT conduit from a box?
The 2008 NEC code states that conduit must be strapped within 36" or 3 feet from every box or connector, then every 5 feet is acceptable from there.
How many No2 Awg THHN wires will fit in a 1 conduit?
Approximately 6-8 No. 2 AWG THHN wires will fit in a 1" conduit, depending on the manufacturer and bending restrictions. However, it is always recommended to consult the National Electrical Code (NEC) and local regulations for specific guidelines on conduit fill for your location.
What percentage is the maximum allowable conductor fill of any trade size conduit used as a raceway?
It depends on the wiring, the current load in the wiring , and the distance. The NEC Code book has the charts for this.And the size of the conduit.
What size rigid conduit for 200 Amp service entrance using 3 ought wire?
For a 200 Amp service entrance with 3/0 AWG wires, you would typically use a 2-inch rigid metal conduit to meet the National Electrical Code (NEC) requirements for maximum fill capacity and ease of installation. Always consult local codes and a licensed electrician for specific installation requirements.
How many 10 awg thhn wire can fit in half inch emt?
9-10, but the conduit may not exceed a certain length, or a certain voltage in order for you to "legally" do it. Many applications allow for conduit fill ratio's that exceed the standards of the NEC ( National Electrical Code) and most of them are short (less than 24") "chases" between control devices mounted in listed Junction boxes for that purpose. It is not advisable to fill a conduit more than the NEC allows for purposes of heat dissipation.
